Polacanthoides (meaning like Polacanthus) is an invalid genus of nodosaurid dinosaur from Europe.[1] It lived about 140 to 135 million years ago in what is now England. It was named by Nopsca in 1928. The type specimen is NHMUK 2584. It is a junior synonym of both Hylaeosaurus and Polacanthus and was based on a chimera of skeletal elements.[2]

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
